Description

[Detailed explanation of the invention] This invention was devised for the purpose of improving the glowing property of the red-hot body installed in the combustion zone of the combustion chamber that burns liquid, gas, and solid fuel, and dissipating a large amount of radiant heat. It is.

The configuration will be explained below with reference to a diagram used in a pot-type liquid combustor as an example.・４・・
All or some of the unopened parts between the ventilation holes 4 and 4 have an auxiliary small hole 5 with a smaller diameter than the ventilation hole 4 approximately in the middle.
・It pertains to a red-hot body provided with.

In the figure, 6 is a pot burner installed in the combustion chamber 1, 7 is a combustor stand, 8 is an oil amount regulator that adjusts the fuel supply to the pot 6, and 9 is a blower that blows combustion air to the pot burner 6. .

Reference numeral 1' designates a heat transmitting body provided at a suitable location on the outer shell of the combustion chamber 1.

This invention with the above configuration is a pot burner 6.
When fuel is supplied to the combustion chamber 1 and ignited in an appropriate manner, combustion begins within the combustion chamber 1.

Therefore, the red-hot body 3 provided in the combustion zone 2 is heated by the combustion heat.
Heats up and becomes red hot.

This incandescent body 3 transmits a large amount of heat rays to the outside through the heat transmitting body 1', etc., and is used for heating, and the unburned gas from the combustion comes in contact with the hot incandescent body 3 and plays a role in promoting combustion. It also has the following.

The more uniformly the entire part of the incandescent body 3 is made red hot, the more radiant heat will be emitted, and the more it will fulfill its role as a combustion accelerator,
Although the visual effect of heating is enhanced, it is also difficult to uniformly heat the entire incandescent body.

That is, if the aperture ratio of the incandescent body 3 is increased, the degree of incandescence will be improved because there will be fewer unopened areas, but the incandescent area will be reduced and the strength will be impaired, so it is not desirable to make the ventilation holes too large.

Therefore, in this invention, a vent hole 4 with a diameter that maintains the unopened area (red-hot area) to the extent that it can be maintained as the optimal area for the device is bored, and the diameter is smaller than the vent hole 4 approximately in the middle of the unopened area. Since the auxiliary small hole 5 is provided, the incandescent body 3 is connected to the ventilation hole 4.
Red heat started from both the vicinity of the hole and the vicinity of the hole of the auxiliary small hole 5, and the degree of redness of the unopened portion was increased compared to the case where the auxiliary small hole 5 was not provided.

As described above, this invention that increases the degree of incandescence without reducing the incandescent area has great utility, and can be applied to either a cylindrical or plate-shaped incandescent body 3.

Although the diameters of the vent holes and the auxiliary small holes are determined by the amount of combustion, it is desirable that the ratio of their diameters be 2:1.
